Recognizing them.. I have a bike with those, they fall out as soon as you loosen the fork/stem bolts..
So I may learn something here. My read from the pics is that the OP has sealed bearings, seated in a steel cup, pressed into his alloy frame. No?
OP, I may have misread the pics. If you can get that retaining ring out, and you have a set of ball bearings in a retainer, then this proves I was wrong. I'm beginning to think I am.
If so, then you would need to replace the headset if you want to go "all new". Or, you could clean the bearings and the races with mineral spirits, and regrease the thing, and reassemble.
